Abstract:

The paper deals with the influence of gear weight reduction on its modal properties. The aim of thepaper is to use the simulation tools to introduce the dependence of natural frequencies on the change in the shape of the gear, which is reflected in the change in weight. At the beginning of the paper, the theory and experimental bases of vibration testing and analysis are introduced to understand the principles of modal parameter specification. Verification of the boundary conditions used in the simulation was performed using the experimental method and it is described in the next part of the article. Tests confirmed the consistency of the values achieved by both approaches. Thus, the same boundary conditions could be used to specify the dependence of natural frequencies on the change in the geometry ofthe gear (which is associated with weight reduction). Numerical analysis was performed by FEM analysisusing PTC Creo software. Experimental modal analysis was performed using a PULSE measurement system.

Abstract:

This paper describes configuring the virtual horizontal machining center LOLA HBG80 within the programming and verification system and the open architecture control system. The horizontal machining center LOLA HBG 80 is represented by an equivalent virtual machine in a CAD/CAM environment (PTC Creo and Catia), STEP-NC Machine environment, and the control system. Virtual simulation is essential for machining, and the developed virtual machines are used for program verification and monitoring of the machining process. The virtual machine in the programming system allows the verification of the program before sending it to the real machine and includes verification of the tool path (CLF-Cutter Location File) and G-code. The paper also discusses the possibility of applying a new programming method known as STEP-NC and preparing an adequate environment that includes a virtual machine. The virtual machine in the control system represents the last level for the final program verification and the process monitoring system.

Abstract:

The banana screen is a device used to classify materials widely used in screenings factories at home and abroad. It's working ability depends on many factors (kinematic parameters, technological parameters, particle size, and material moisture,...). If using the traditional method to determine suitable parameters to reach high efficiency, it is very difficult. Because the calculated results are not accurate, it takes a designer much time and makes the manufacturing cost increase. In this study, the author uses the computer software CREO, ADAMS, ANSYS to design and simulate the dynamics of the screen. The results of study are the dynamic parameters of the screen during the working time and are shown in different graphs (Elastic pillow deformation of spring; the force exerted on the elastic pillow; the center velocity of vibration box; center acceleration of vibration box; static energy of vibrates box; translational momentum of vibration box; moment momentum of vibration box). These results also can be applied to design banana screens, which have a high capacity and efficiency as well as a long lifetime.

Abstract:

In the field of Engineering and Technology, Gear is one of the most significant and essential component in mechanical power transmission system. General devices have major applications in various fields like automotives, industrial rotational machines, lifting devices, etc. Gears are usually subjected to fluctuating loads while in action. Gear tooth mainly fails due to excessive bending stress and excessive contact stress. Thus while designing the gear it is very necessary and vital to analyze the stresses induced in the gear for its safe operation. Weight reduction of gear is also one of the main design criteria as it has a great role in improving the efficiency of the entire system. Nowadays engineering components made up of composite materials and plastics find increasing applications. The components made by the composite materials provide reasonable mechanical properties with minimum weight. The objective of this research is to develop the spur gear and pinion assembly model using engineering simulation PTC Creo and imported to 3-D design software ANSYS workbench 16.0 for working on the static structural analysis. The analysis was carried out by considering different materials for gears like structural steel, polycarbonate and 20%AlSiC. From the observed results it was found that, 20%AlSiC composite material has mass reduction of about 45%, hence it is suitable for light weight applications.

Abstract:

Industry 4.0 represents a new paradigm which creates new requirements in the area of manufacturing and manufacturing metrology such as to reduce the cost of product, flexibility, mass customization, quality of product, high level of digitalization, optimization, etc., all of which contribute to smart manufacturing and smart metrology systems. This paper presents a developed inspection planning system based on CMM as support of the smart metrology within Industry 4.0 or manufacturing metrology 4.0 (MM4.0). The system is based on the application of three AI techniques such as engineering ontology (EO), GA and ants colony optimization (ACO). The developed system consists of: the ontological knowledge base; the mathematical model for generating strategy of initial MP; the model of analysis and optimization of workpiece setups and probe configuration; the path simulation model in MatLab, PTC Creo and STEP-NC Machine software, and the model of optimization MP by applying ACO. The advantage of the model is its suitability for monitoring of the measurement process and digitalization of the measurement process planning, simulation carried out and measurement verification based on CMM, reduction of the preparatory measurement time as early as in the inspection planning phase and minimizing human involvement or human errors through intelligent planning, which directly influences increased production efficiency, competitiveness, and productivity of enterprises. The measuring experiment was performed using a machined prismatic workpiece (PW).

Abstract:

Abstract The use of integrated Computer Aided Design/Engineering (CAD/CAE) software capable of analyzing mechanical devices in a single parametric environment is becoming an industrial standard. Potential advantages over traditional enduring multi-software design routines can be outlined into time/cost reduction and easier modeling procedures. To meet industrial requirements, the engineering education is constantly revising the courses programs to include the training of modern advanced virtual prototyping technologies. Within this scenario, the present work describes the CAD/CAE project-based learning (PjBL) activity developed at the University of Genova as a part of course named Design of Automatic Machines, taught at the second level degree in mechanical engineering. The PjBL activity provides a detailed overview of an integrated design environment (i.e. PTC Creo). The students, divided into small work groups, interactively gain experience with the tool via the solution of an industrial design problem, provided by an engineer from industry. The considered case study consists of an automatic pushing device implemented in a commercial machine. Starting from a sub-optimal solution, the students, supervised by the lecturers, solve a series of sequential design steps involving both motion and structural analysis. The paper describes each design phase and summarizes the numerical outputs. At last, the results of the PjBL activity are presented and commented by considering the opinions of all the parties involved.

Abstract:

To optimize the dimensions of the boom, stick of the hydraulic excavator and select the suitable hydraulic bucket, stick, and boom cylinders, the designer must determine the joint reaction forces and driving forces. These forces always alter in an excavator's working cycle. They are conventionally calculated by mathematical method. This conventional method is complicated and challenging to determine the maximum reaction forces, which can break the stick and boom. This article builds a 3D model and simulates a working cycle of the hydraulic excavator to find the reaction force diagrams of boom and stick as well as driving forces of hydraulic cylinders by using computer software PTC Creo Parametric. Based on these results, the designer easily calculates the maximum tensions of the dimensions of boom and stick in a working cycle to optimize their dimensions as well as selects suitable hydraulic cylinders.

Full text

Abstract:

Two-dimensional (2D) Unsteady Reynolds-Averaged Navier–Stokes equations (URANS) equations with the Spalart–Allmaras turbulence model are used to simulate the flow and body kinematics of the transverse motion of spring-mounted circular cylinder. The flow is in the high-lift TrSL3 regime of a Reynolds number in the range 35,000 < Re < 130,000. Passive turbulence control (PTC) in the form of selectively distributed surface roughness is used to alter the cylinder flow induced motion (FIM). Simulation is performed using a solver based on the open source Computational Fluid Dynamics (CFD) tool OpenFOAM, which solves continuum mechanics problems with a finite-volume discretization method. Roughness parameters of PTC are chosen based on tests conducted in the Marine Renewable Energy Lab (MRELab) of the University of Michigan. The numerical tool is first tested on smooth cylinder in vortex-induced vibration (VIV) and results are compared with available experimental measurements and URANS simulations. For the cylinder with PTC cases, the sandpaper grit on the cylinder wall is modeled as a rough-wall boundary condition. Two sets of cases with different system parameters (spring, damping) are simulated and the results are compared with experimental data measured in the MRELab. The amplitude ratio curve shows clearly three different branches, including the VIV initial and upper branches, and a galloping branch. The numerical branches are similar to those observed experimentally. Frequency ratio, vortex patterns, transitional behavior, and lift are also predicted well for PTC cylinders at such high Reynolds numbers.

Medicine and Pharmacy Reports, March 25, 2020. http://dx.doi.org/10.15386/mpr-1312.

Full text

Abstract:

Introduction. One of the principle factors for the success of implant supported/retained overdentures (IOs) is the manner in which the stresses are transferred to the surrounding bone. Hence, the aim of the present study is to compare the stress induced in the mandible around IOs, using two different attachment systems, locator and telescopic. Methods. 3D finite element models were prepared using Pro/ENGINEER or PTC Creo to simulate 4 clinical situations: IOs using two different attachment systems, locator and telescopic, with and without splinting. A vertical compressive load of 35N was directed toward the central fossa in the molar region of each overdenture. Non-linear static contact analysis was carried out to determine the stress distribution in various components of IOs. Then, the models were analyzed by a finite element program ABAQUS, and displayed using Von Mises stress patterns. Results. The contact stress values developed on the implant and attachment components were lower with locator attachment, in both splinted and non-splinted models. On the other hand, the stress distribution to the cortical bone was more with non-splinted/splinted locator attachments (3.73/4.12 Mega Pascals) when compared to the non-splinted/splinted telescopic attachments (2.66/3.7 Mega Pascals). The stresses in all the components of overdenture were greater with the splinted model compared to non-splinted, in both the attachment systems.  Conclusion. The locator attachment might demonstrate superior clinical performance, as the stresses on implant and attachment components were less compared to telescopic. Non-splinted model showed better results in both the attachment types.

Abstract:

A performance comparison of a Pulse Tube Cryocooler (PTC) that uses inertance tube- bounce space and inertance tube-reservoir as a phase shifter is conducted using numerical simulations. The initial design cryocoolers were carried out using Sage software. A CFD model was developed using ANSYS Fluent to analyze the Cryocooler performance. The CFD model was used to simulate the effect of different volumes of reservoir and bounce space on Cryocooler performance. The thermal non-equilibrium mode was chosen to consider the effect of temperature difference between solid and fluid temperature difference in porous zones. The numerical model was validated with experiments from referred journal. The simulation results showed a phenomenal increasing trend in cooling capacity up to 400cm3 , and thereafter, a marginal increment in performance with increase in volume. The Stirling cryocooler with inertance tube-bounce space as phase shifter has over performed the cryocooler with inertance tube-reservoir. The COP of cryocooler with 400cm3 bounce volume was found to be 0.042, is 1.38 times higher than that of 200 cm3 and for higher volumes difference in COP was less significant.

Abstract:

This paper aims to conduct modeling and simulation of a Concentrated Solar Power (CSP) Plant in Ber’Alganam area (Azzawia-Libya). The thermal analysis of the solar power plant was carried out to identify its characteristics and present the monthly power curves according to measured solar radiation and meteorological data of Ber’Alganam (Azzawia-Libya). The mathematical model of the plant was based on energy balance of each component used to develop the simulation tool using Matlab software. The simulation tool can be used to simulate the solar plant and achieve desired plots and results. Among many techniques used in the field of solar power generation, the Concentrated Solar Power (CSP) technology using Parabolic Trough Collector (PTC) or (PT) has been selected. As a sample case, a 30 MW CSP plant was proposed to present the hourly performance and productivity through entire year. The study offered a description of two more technologies; thermal energy storage (TES) and backup boiler in order to enhance and stabilize the CSP plant and the continuous production throughout daytime and estimate the amount of fuel needed for this issue, the results shows, the annual power output by both solar source, TES system, and the backup boiler are 91513, 318.36, and 4690.45 MWh/year, respectively, with respect the solar multiplier is 1.5. The study also concerned with the amount of emissions avoided by using CSP plants, the study estimated that, 18516.4 tons of emissions could be annually avoided by CSP plant rather than conventional plant that uses a natural gas as the energy source. The results demonstrate that, the Ber’Alganam is a good location to construct CSP plants, according to the productivity indicators.
